One, suck phlegmy the preparation before works 1 should make sure negative pressure attracts plant above all each conduit joins correct, close together, unobstructed, assure significant negative pressure, general adult 10.64~15.96Kpa, the baby should be controlled in 7.98~10.64Kpa. 2 preparation rinse the asepsis physiological saline that smokes phlegmy pipe 2 bottles, 1 bottle wash pump technically with Yu Chong the suction inside tracheal spile is phlegmy canal , additional 1 bottle rinse those who had sucked mouth, nasal cavity technically to smoke phlegmy pipe . 3 equipment are very different the asepsis of model sucks phlegmy canal and asepsis glove. 4 because suck phlegmy itself,be a kind of stimulation to the patient, sober patient is not willing to suck normally phlegmy, and the family member of insensible patient also thinks to suck phlegmy special anguish.

一、吸痰前的预备工作1首先要保证负压吸引装置各管道连接正确、紧密、通畅，保证有效的负压，一般成人10.64~15.96Kpa，婴儿应控制在7.98~10.64Kpa.2预备2瓶冲洗吸痰管的无菌生理盐水，1瓶专门用于冲洗抽吸气管插管内的吸痰管，另1瓶专门冲洗吸过口、鼻腔的吸痰管。3备好不同型号的无菌吸痰管及无菌手套。4由于吸痰本身对病人是一种刺激，清醒的病人通常不愿意吸痰，而昏迷病人的家属也认为吸痰非凡痛苦。

For example, self-cleaning by current-heating provides clean cap surface and stable FE characteristics; a capped CNT can be opened controllably.

比如清洁闭口管的表面，从而获得稳定的发射；或可控地打开闭口管的&帽子&。

Retrospectively analyses 125 cases respiratory failure patients remedied by tracheal intubation in our hospital from 2001-04 to 2004-09. Comparing achievement ratio, time of detained airtube,incision of trachea ratio, extubate ratio, and sufferers' post-recovery condition of nasal trachea cannula under the guidance of fibrobronchoscope and oral trachea cannula under the guidance of laryngeal endoscope.
